Acetylcholine esterase is an important enzyme in neural synaptic signal transmission. It breaks down the neurotransmitter acetylcholine after it binds the acetylcholine receptor. Its active site has the same features used by serine proteases. Here is the reaction catalyzed by Acetylcholine esterase: Acetylcholine Choline OH Acetate + H Acetylcholine is an ester, while peptide bonds cleaved by proteases are amides. How should acetylcholine estease's mechanism accommodate this? This cannot be determined from the information presented in class and in this question. For amides, the amide nitrogen is deprotonate to make it more like an ester. The same mechanism cleaves deprotonated amides and esters. No changes are needed. The mechanism same works for esters and amides. Prior to cleavage, a transamination converts the ester to an amide. The esterase will make a covalent intermediate to an amine to create the amide to be cleaved.

Neostigmine is an inhibitor of acetylcholinesterase. The enzyme attempts to catalyse the same reaction on neostigmine as it does with acetylcholine. However, a stable intermediate is formed which prevents completion of the process and which results in a molecule being covalently linked to the active site. Identify (draw) the stable intermediate and explain why it is stable.

A key step in the hydrolysis of acetamide in aqueous acid proceeds by nucleophilic addition of * OH (a) H3O* to CH3Ĉ NH2 (b) H2O to CH3ČNH2 + OH +OH (c) H3O* to CH,ČNH2 (d) HO¯ to CH3CNH2
